<a name="GDBusProxy.description"></a><h2>Description</h2>
<p><a class="link" href="GDBusProxy.html" title="GDBusProxy"><span class="type">GDBusProxy</span></a> is a base class used for proxies to access a D-Bus
interface on a remote object. A <a class="link" href="GDBusProxy.html" title="GDBusProxy"><span class="type">GDBusProxy</span></a> can be constructed for
both well-known and unique names.</p>
<p>By default, <a class="link" href="GDBusProxy.html" title="GDBusProxy"><span class="type">GDBusProxy</span></a> will cache all properties (and listen to
changes) of the remote object, and proxy all signals that gets
emitted. This behaviour can be changed by passing suitable
<a class="link" href="GDBusProxy.html#GDBusProxyFlags" title="enum GDBusProxyFlags"><span class="type">GDBusProxyFlags</span></a> when the proxy is created. If the proxy is for a
well-known name, the property cache is flushed when the name owner
vanishes and reloaded when a name owner appears.</p>
<p>If a <a class="link" href="GDBusProxy.html" title="GDBusProxy"><span class="type">GDBusProxy</span></a> is used for a well-known name, the owner of the
name is tracked and can be read from
<a class="link" href="GDBusProxy.html#GDBusProxy--g-name-owner" title="The “g-name-owner” property"><span class="type">“g-name-owner”</span></a>. Connect to the <a href="https://developer.gnome.org/gobject/unstable/gobject-The-Base-Object-Type.html#GObject-notify"><span class="type">“notify”</span></a> signal to
get notified of changes. Additionally, only signals and property
changes emitted from the current name owner are considered and
calls are always sent to the current name owner. This avoids a
number of race conditions when the name is lost by one owner and
claimed by another. However, if no name owner currently exists,
then calls will be sent to the well-known name which may result in
the message bus launching an owner (unless
<a class="link" href="GDBusProxy.html#G-DBUS-PROXY-FLAGS-DO-NOT-AUTO-START:CAPS"><code class="literal">G_DBUS_PROXY_FLAGS_DO_NOT_AUTO_START</code></a> is set).</p>
<p>The generic <a class="link" href="GDBusProxy.html#GDBusProxy-g-properties-changed" title="The “g-properties-changed” signal"><span class="type">“g-properties-changed”</span></a> and
<a class="link" href="GDBusProxy.html#GDBusProxy-g-signal" title="The “g-signal” signal"><span class="type">“g-signal”</span></a> signals are not very convenient to work with.
Therefore, the recommended way of working with proxies is to subclass
<a class="link" href="GDBusProxy.html" title="GDBusProxy"><span class="type">GDBusProxy</span></a>, and have more natural properties and signals in your derived
class. This <a class="link" href="gdbus-example-gdbus-codegen.html" title="Using gdbus-codegen">example</a> shows how this can
easily be done using the <a href="gdbus-codegen.html">gdbus-codegen</a> tool.</p>
<p>A <a class="link" href="GDBusProxy.html" title="GDBusProxy"><span class="type">GDBusProxy</span></a> instance can be used from multiple threads but note
that all signals (e.g. <a class="link" href="GDBusProxy.html#GDBusProxy-g-signal" title="The “g-signal” signal"><span class="type">“g-signal”</span></a>, <a class="link" href="GDBusProxy.html#GDBusProxy-g-properties-changed" title="The “g-properties-changed” signal"><span class="type">“g-properties-changed”</span></a>
and <a href="https://developer.gnome.org/gobject/unstable/gobject-The-Base-Object-Type.html#GObject-notify"><span class="type">“notify”</span></a>) are emitted in the
<a href="https://developer.gnome.org/glib/unstable/glib-The-Main-Event-Loop.html#g-main-context-push-thread-default">thread-default main context</a>
of the thread where the instance was constructed.</p>
<p>An example using a proxy for a well-known name can be found in
<a class="ulink" href="https://git.gnome.org/browse/glib/tree/gio/tests/gdbus-example-watch-proxy.c" target="_top">gdbus-example-watch-proxy.c</a></p>

<p>Normally you will not need to use this method since <em class="parameter"><code>proxy</code></em>

is tracking changes using the
<code class="literal">org.freedesktop.DBus.Properties.PropertiesChanged</code>
D-Bus signal. However, for performance reasons an object may
decide to not use this signal for some properties and instead
use a proprietary out-of-band mechanism to transmit changes.</p>
<p>As a concrete example, consider an object with a property
<code class="literal">ChatroomParticipants</code> which is an array of strings. Instead of
transmitting the same (long) array every time the property changes,
it is more efficient to only transmit the delta using e.g. signals
<code class="literal">ChatroomParticipantJoined(String name)</code> and
<code class="literal">ChatroomParticipantParted(String name)</code>.</p>
